To all whom it may concern: 3 1 Be it known that I, Gnoncn EYERS, a citizen of the United States, rcsitlin at Marshfielcl, in the county of Wood. and: tnte of Wisconsin, have inventeda new and use ful Road-Scraper, of which the following is a specification.

This invention relates to road scrapers, one of its objects being to rovicle a simple and compact structure of this character which wlil operate elliciently to level oil roads by removing ridges and the like and filling in depressions with the loose dirt. thus gathered.

Another object is to provide a scraper the blades of which are adjustable and are constantly under the control of the operator.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement. oi parts arul in the details of construction hereinafter tit-scribed and claimed, it. being understood that changes in the precise cmbmlimcnt ot the invention herein ills-closed, can be made Within the scope of whatis claimed, without departing; froni the spirit. of the invention. In the accompanying drawings the pre tcrretl form of the invention has been. shown.

In said drawings: l igure 1 is a plan View of the scraper. Fig. 2 is n side elevation thereof. Fig. 3 is a section on line A-B Fig. l and showing the blade tilted to bring the supporting wheel to active position.

Referring to the figures by characters of reference it designates a draft beam having; a cross strip 2 secured to the rear end there-- of. The beam 1 extendsbetween forwardly diverging scraping blades 3 [)IOVltiOtl. along their up )Ol edges, with forwardly extend-- ing reintoreing flanges 4-. The rear cnti portions of the blades are connected to the ends of the cross strips by eye bolts 5 or the like whereby hinge connections are formed between said cross strip and the scraping blades. Eye bolts (3 are also secured to the blades at points adjacent. the centers thereof and are connecteti, as by means of forwardly converging links 7 to ears 8 extending lat.- erslly from the beam'i. Additional ears 9 extend laterally from the beam at points between the cross strip 2 and the ears 8 and are connected, by means of rearwartlly diverging links 10, to eye bolts 11 secured to tact with the f ltOlulfii.

i the blades 3. llearweroily extending creel:

ets 12 are secured to the blatlcs and carry small vneels 13 'irliicli,'when the blades are in ilVt. positions, are supportcci out. of'cow A. lever 1%, IS fillet-timed as at -15, npon toothed segment; l6v upstanding :trcni the beam 1 and connected to this lever are rea wartily diverging links 1?, the rear cntls of which are secured to npstnntiing arms 18 upon the rear ends of the scraper blaxies Lover 14 has a spring presse-zt pawl 19 for engaging the toot-hen. segment it: wl'lorchy said lever can be. locked in tiny position to which it may be adjusted. i

lit will be apparent; that; when the inner 1% is in upstanding position, the lower: edges of the scraping blades 3 will lie in conic. a; with the surface to be noted on so that when its the beam it is drawn forward, these blades will scrape said surface and. deflect the loo-s enetl soil inwardly toward the center of space between the blades. By providing the link connections between the blades anal the beam. saitl blades are free to tie}; tn'lwsrdly anrl dowmvartlly to a. certain extcntso as to contorn'i automatically to any irregularities in the general contour of "the suriiace over which the scraper is (llfAVlL Should it be desired to shift the blades out of active po sitions, lever 14 is swung rcarwnrdly as to cause the links 1'? to press outwardly upon the arms 18. The blzuies 3 will thus be rotated about; lines extending through the no connections between the links I and 10 and the blades and, as o result the bracketslfi: and wheels 13 will. be swung tiownwcrtliy so as to thus bring the whet-is in contact with tit the ground. ll then looking the lever 14; against further movement, it will be seen that the wheels will. trcrci along the ground alnl the ma ter. will be supportcci out; of contact with the nronnil. 1 What is fliillmtlil 117,;-

The combination with s tire-it. boom anti :2. cross strip at one cool thereof, of fore-er it diverging scraping blmiea. eye bolts con nectecli to each blade, one bolt on with blade mornbly engaging one. 9nd of. the 7 1 h? cross strip, front and rear pairs of i connected to the remaining eye boltsa links of each air, converging; itcrwnrtigr W... being'pivotal y connected to the sitics oi the beam, rcarwnrtlly extending brncitets ocuretl to the blades adjncent' the centers thereof whee-ls journalcd Within the. bracts ets, upwardly extending arms fixedl connecked te the-rearend portions of the lades,

a lever fulcrumed on the beam, and vlink connections between said lever and the re,

spective arms, said lever and cdn nectlions constltutmg means for slmultaneously rotating the blar .s about their respective longi-' tudinal axes to bring either the wheels or the lower edges of the blades into contact,

with the glipt mtl, apd jr eans 9; holding the Witnesses lever in any positiofi to which it hiayhe shifted. v

a In testimony that I claim the foregeil lgfas my own, I have-hereto aflixed m signature inthe presence of two witnesses.
